    Important Warning

    The underlying v8 API used by this native addon is still experimental, and binary compatibility may not be guaranteed between data output by the same application running in two different node versions.

    If you plan to use this over a wire, please bear that in mind.

    Compatibility

    • node.js >= v8.13.0 (LTS/Carbon)

    Usage

    Use npm install serialism to install the npm package.

    TypeScript

    import { assert } from 'chai';
    import { Serialism } from 'serialism';
    import { Class1 } from '...';
     
    const serialism = new Serialism();
    // or if you plan on serializing a value containing ES6 classes:
    // const serialism = new Serialism([Class1, Class2, ...]);
     
    // serialize an object, an array, a regex, a primitive value, anything works except local symbols
    const myArray = [1, 2, NaN, /my-regex-here/g, new Class1('ho there!')];
     
    // cyclic and self-references will work
    myArray.push(myArray);
     
    const data = serialism.serialize(myArray);
     
    console.log(Buffer.isBuffer(data)); // true;
     
    const deserialized = serialism.deserialize<any>(data); // deserialize the data
     
    assert.deepEqual(data, deserialized); // true, the clone is equal
     
    assert.instanceOf(
      serialism.deserialize<Class1>(serialism.serialize(new Class1("I'm a class"))),
      Class1
    ); // true

    JavaScript

    const Serialism = require('serialism').Serialism;
    const Class1 = require('...');
     
    // serialize an object, an array, a regex, a set, a map, a primitive value, anything works except local symbols
    const data = serialism.serialize([
      1,
      2,
      NaN,
      new Map(),
      new Set(),
      /my-regex-here/g,
      new Class1()
    ]);
     
    console.log(Buffer.isBuffer(data)); // true;
     
    const deserialized = serialism.deserialize(data); // deserialize the data
     
    assert.deepEqual(data, deserialized); // true, the clone is equal

    Raw interface (no class deserialization)

    This allows you to serialize and deserialize any JavaScript value, without the revival of classes and the processing of global symbols.

    This interface is much faster because it will not traverse the object graph in JavaScript to entomb and revive values.

    In this case, any class instances supplied will be serialized as plain objects.

    import { serializeNative, deserializeNative } from 'serialism';
    import { assert } from 'chai';
     
    const target: any = {
      undef: undefined,
      nullVal: null,
      negativeZero: -0,
      test: 'hello world',
      array: [1, 2, 3, 'test', Math.PI, new Date()],
      map: new Map<any, any>([['hi', 3], [Infinity, 'test'], [NaN, null]]),
      set: new Set<any>([1, 2, 3, +0, null, undefined]),
      regexp: /hello-world/g,
      instance: new Dummy(),
      str: new String('string object instance'),
      num: new Number(100),
      object: {
        'test long key': 'value',
        emptyString: ''
      }
    };
     
    // create some basic and deeply nested cyclic dependencies
    target.cyclic = target;
    target.map.set(target, target.set);
    target.set.add(target);
    target.map.set(target.array, target.instance);
     
    const data = serializeNative(target);
     
    const result = deserializeNative(result);
     
    assert.deepEqual(target, result); // true
